Original Description

Central chamber a little larger than both cupolas. From the surface arise twelve strong conical radial spines, four on the poles of the major and the minor axis of the shell, lying in the lateral plane; eight others lying in two diagonal planes, as prolongations of the eight wing-beams, which connect the Tetrapyle-shaped medullary shell with the two ring-like constrictions of the cortical shell. Pores of the latter irregular, roundish, twice to four times as broad as the bars sixteen to eighteen in the basal semicircle of one cupola.

Major axis of the shell 150µm, minor 110µm; pores 4 to 8µm, bars 2µm.

Editors' Notes
